PROCESS OF PURIFYING GAS.

SPECIFICATION formingpart of Letters Patent No. 727,266, dated May 5, 1903. Application filed August 6, 1901. Serial No. 71,058. (No specimens.)

T0 aZZ whom it may concern:

Be it known that I, JAMES ALEXANDBE BELLON-LENCAUCHEZ, (called J. A. LENCAU- CHEZ,) a citizen of the Republic of France, and a resident of Paris, France, have invented a new and useful Improvement in the Purification of HighFurnace andLike Gases, which is fully set forth in the following specification.

ess of purifying gases such as those obtainedfrom gas-generating furha'cs, high f urnaces; drc.,which,as is well kn own,often carrya large amount of suspended matter which cannot be: eliminated satisfactorily even in the most per fectly-constructed scrubbers or other existing. wash i ng apparatus. 7 The dust carried 7 and suspended in the gases of high furnaces and referred. to bymanufacturers as sublimed is composed of silica, lime, aluinina, magnesia, oxid' of iron, carbonates oflime and magnesia, and other substances in the formoflimpalpable powdered substances of a greasy na-ture,-whi'ch-. are capable of traversing the various chan nels, galleries, and lines ofthe gas-genera tor without becoming deposited and which finally escape through the chimney, notwithstanding the height thereof of fifty meters to seventy meters, and spread over distances of more than eight or ten kilometers area.- These objectionable dusts have. hitherto resisted The improved process of purification according to this invention enables, say, high furnace gases to be treated and purified in a perfect manner; but other gases obtained from various other forms of generators, such as gas-generator furnaces, 850., may equally be treated.

In carrying out my process instead of employing towers or other washers or scrubbers, which occupy large: spaces, 1- prefer to arrange at .any convenient' point in the conduits for the gas a centrifugalfan or turbinewheel, into which is directedby any convenient means and at any pressure a cold or hot water current or currents. The centrifugal force of the said fan or turbine produces an intimate contact between and commingling of the gas and the water introduced therein,

fis-a plan. l. llhe apparatus comprises two oppositelyand thereby enables the water to completely free the gas of its suspended impurities. This is the characteristic principle of my invention, and; as will be understood, in practice the construction of the fan may be varied to suit diiferent requirements; butIhave found the form of apparatus hereinafter described to give good general results.

'Referring.to the accompanying drawings,

arranged wheels j j, mounted on the inner ends of shafts 7c k, respectively, which shafts areladapted to be rotated 'infopposite direc- ;tions' by any suitable fmeehanism. (Not shown.) Two series of flatf'blades 1 and 3 a'resecur'ed to wheelj near its periphery and :pji oject into close proximity with the adjacentfaceiof wheel j, as clearly shown in Fig. '2',".'and similar series of blades 2 and 4 are in like mannersecured tow-heel jand project intoJ'close.proxijmity-to wheel j, the disposh tion Oftheseriesof blades being such that on the rotation of the wheels blades 2 travel :inwafspace between blades 1 and 3, while b1ades' 3 travel in a space between blades 2 and a, all as clearly shown in Figs. 1 and 2. A is a gas-supply conduit bifurcated at its delivery endto form passages a at, the former terminatingat the side of wheel j and the latter at theside of wheel j. Shaft k at its inner end is-journaled in a bearing 6, supported upon the bottom of passage a, Fig. 4, and at its outer end passes through stufling-box c in side plate I) of passage a and is journaled in astandard d. Shaft it is supported in similar bearings. This arrangement permits the outer hearings to be mounted in position after the assembling of the inner parts of the apparatus and enables the same tobe mounted in a perfectly level position;

ff, Figs. 2 and3, are water-delivery nozzles which project through the wallsof passages a, a, and project water from opposite sides in the form of a spray between the .spokes of wheels j j and into the space between the lower parts of said wheels, where it is at once subjected to the action of the moving blades.

The inner bearings e maybe lubricated by means of externally-located oil-pots g, Fig. 2, each provided with a supply-tube h, leading to the hearing.

In the operation of the apparatus the gas delivered from passages a a and the water delivered from nozzles ff into the space between the centrifugal wheels jj is first acted upon by the series of blades 1, which project the mixture by centrifugal force against the second series of blades 2, moving rapidly in a direction opposite to that of blades 1,thus subjecting the mixture to violent and repeated shocks, which are repeated as the mixture is passed by centrifugal action from blades 2 to 3 and in turn from blades 3 to t. The

blades 4 expel the mixture into the exit-conduit B. By reason of the violent shocks to which the gas and water are subjected the latter is atomized and intimately mixed with the gas, both being moved in the same direction by centrifugal force, and the suspended dust. or other matter in the gas is thoroughly subjected to the action of the water and after having been moistened thereby settles in the form of greasy slime.

What I claim, and desire to secure by Letters Patent of the United States, is

1. The herein-described process of purifying gas consisting in intimately commingling the gas with a washing liquid by simultaneously agitating the gas and liquid together by centrifugal force causing the gas and liquid introduced at or near the center of rotation to move in the same direction on from the center toward the circumference with re-. lation to the axis of rotation and the liquid to be atomized and intimately mixed with the gas.

2. The herein-described process of purifying gas consisting in projecting a washing liquid in the form of a spray into contact with the gas, then atomizing the washing liquid and intimately commingling the gas with the liquid by simultaneously agitating the gas and liq uid together by centrifugal force causing, the gas and liquid introduced at or near the center of rotation to move in the same direction from the center toward the circumference with relation to the axis of rotation at the same time subjecting the mixture of gas and liquid to repeated impacts or shocks.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
